Plotly is a new tool I’ve recently come across for sharing interactive graphs. Its effectively an API that allows you to pump graphs to the web using various coding languages; currently R, Python and Matlab. It automatically adds an element of interactivity to the graphs using java script. Its then easy to share those graphs with other people. Its business model works in a similar way to github and bitbucket. It’s free if you are happy to share your output with the world but you have to pay for privacy. So for bloggers and open source enthusiasts its a useful free tool.
There are plenty of instructions on the site to guide you through using it, but here’s a quick overview of using it in R from me.
